Bug 1422931 - Part 2: Make webcomponents preference per-doc. r=smaug

Browse Source 
This is to fix the case where preference is restore to false when a testcase
ends, but nsDocument::DeleteShell is called afterwards. So, we make the
preference per-doc and set it when the document is created. The value does not
change for the lifetime of the document.
